If the length of one side of a square is 12.0 m, what is the perimeter of the square in units?

48.0 is the perimeter of the square in meters.

Explanation:

Perimeter is defined as sum of all sides.

Length of the square = l = 12.0 m

The formula of the perimeter of the square follow:

Perimeter of the square = P = 4 × l

Putting the values is above formula :

48.0 is the perimeter of the square in meters.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
